TECHNICAL FIELD

The present invention relates to the wireless communication field, andin particular, to a method and system for indicating transmissionparameter.

BACKGROUND OF THE RELATED ART

In the wireless communication technology, when the base station side(for example the evolved node B, that is eNB) transmits data by usingthe a plurality of antennas, the way of the spatial multiplexing can betaken to improve the data transmission rate, that is, the sending endtransmits different data in different antenna locations by using thesame time-frequency resources, and the receiving end (such as the userequipment, UE) also receives the data by using a plurality of antennae.The resources of all antennae are distributed to the same one user inthe case of single user, and that user individually occupies thephysical resource assigned by the base station side within onetransmission interval, and this transmission way is called as the SingleUser Multiple-Input Multiple-Output (abbreviated as SU-MIMO); the spaceresources of different antennae are distributed to different users inthe case of multi-user, one user and at least one other user share thephysical resource assigned by the base station side within onetransmission interval, where the share mode can be a space divisionmultiple access way or space division multiplexing way, and thistransmission way is called as the Multiple User Multiple-InputMultiple-Output (abbreviated as MU-MIMO), wherein, the physicalresources assigned by the base station side refers to the time-frequencyresource. If the transmission system needs to support the SU-MIMO andthe MU-MIMO at the same time, then the eNB needs to provide the dataunder these two modes to the UE. The UE needs to acquire the rank usedby the eNB transmitting the MIMO data to the UE no matter in the SU-MIMOmode or the MU-MIMO mode. Under the SU-MIMO mode, the resources of allantennae are distributed to the same one user, the number of the layersused for transmitting the MIMO data equals the rank used by the eNBtransmitting the MIMO data; under the MU-MIMO mode, the number of thelayers used during the transmission corresponding to one user is lessthan the total number of the layers used by the eNB transmitting theMIMO data, and if the switch between the SU-MIMO mode and the MU-MIMO isrequired, then the eNB needs to notify different control data to the UEunder different transmission modes.

The standard of the Long-Term Evolution (abbreviated as LTE) release 8defines the following three kinds of downlink physical control channels:the Physical Control Format Indicator Channel (abbreviated as PCFICH),the Physical Hybrid Automatic Retransmission Request Indicator Channel(abbreviated as PHICH) and the Physical Downlink Control Channel(abbreviated as PDCCH). Wherein, the PDCCH is used for bearing theDownlink Control Information (abbreviated as DCI), including: the uplinkand downlink scheduling information, and the uplink power controlinformation. The DCI format is divided into the following kinds: DCIformat 0, DCI format 1, DCI format 1A, DCI format 1B, DCI format 1C, DCIformat 1D, DCI format 2, DCI format 2A, DCI format 3 and DCI format 3A,etc.; wherein, the transmission mode 5 which supports the MU-MIMOutilizes the downlink control information of the DCI format 1D, and thedownlink power offset field δ_(power-offset) in the DCI format 1D isused to indicate the information of reducing the power of one user byhalf (that is, −10 log 10 (2)) in the MU-MIMO mode. Since the MU-MIMOtransmission mode 5 only supports the MU-MIMO transmission of two users,through this downlink power offset field, the MU-MIMO transmission mode5 can support the dynamic switch between the SU-MIMO mode and theMU-MIMO mode, however, the DCI format only supports the transmission ofone stream for one UE no matter in the SU-MIMO mode or the MU-MIMO mode.Although the LTE Release 8 supports the single user transmission of atmost two streams in the transmission mode 4, since the switch betweenthe transmission modes can only be half static, it cannot perform thedynamic switch between the single user multi-stream transmission and themulti-user transmission in LTE release 8.

In the release 9 of the LTE, in order to enhance the downlinkmulti-antenna transmission, the transmission mode of the dual-streamBeamforming is introduced, and the downlink control information isincreased with DCI format 2B to support the transmission mode. There isone identification bit of the scrambling identity (abbreviated in asSCID) in the DCI format 2B to support two different scramblingsequences, and the eNB can distribute these two scrambling sequences todifferent users and multiplex a plurality of users in the same oneresource. In addition, when only one transport block is enabled, the newdata identification (NDI) bit corresponding to the disabled transportblock is also used to indicate the antenna port in the single-layertransmission.

In addition, in the release 10 of the LTE, the transmission mode of theMIMO has already confirmed that the Demodulation Reference Signal(abbreviated as DMRS) is used as the pilot frequency for thedemodulation, and the UE needs to obtain the position of the pilotfrequency and then can perform the estimation of the channel and theinterference on the pilot frequency. The number of the total layers ofdifferent transmission has different pilot frequency patterns, forexample, three different patterns are preliminarily defined in therelease 10 of the LTE. When the number of the total layers of thetransmission or the rank is 1 or 2, the first pattern (DMRS pattern 1)is used; when the number of the total layers of the transmission or therank is 3 or 4, the second pattern (DMRS pattern 2) is used; when thenumber of the total layers of the transmission or the rank is any valuefrom 5 to 8, the third pattern (DMRS pattern 3) is used. In the SU-MIMOmode, the data in all transmission layers are sent to the same one UE,so the UE can know the pattern of the pilot frequency and can know thepilot frequency position only if it obtains the rank. In the MU-MIMOmode, the UE needs to acquire the rank and the number of the layersstarting to perform the transmission to the UE, and the UE also needs toacquire the pilot frequency pattern for transmission then it can onlyobtain the pilot frequency position. In addition, different DMRS portsuse different spreading codes, and the UE further needs to acquire thespreading code used for transmission and then can only obtain theinformation on the pilot frequency. In the technology of the existingLTE release number 10, the above-mentioned demand is not supported. Inthe LTE release 10, it is already confirmed that the transmission modeof the MIMO is required to support single user transmission of which themaximum number of the total layers is 8, and support the single user andmulti-user transmission in the same one transmission mode, however,signaling of the MIMO multi-user transmission based on the DMRS has notbeen supported yet.

PREFERRED EMBODIMENTS OF THE PRESENT INVENTION

The present invention provides one kind of downlink control informationwith low overhead, which supports the single user and multi-usertransmission for which the maximum of the total number of the layers is8 in the same one signaling at the same time. Considering the problemthat the release number 10 of the LTE in the related technology does notsupport the MIMO multi-user transmission based on the demodulationreference signal, the embodiment of the present invention provides amethod and system for indicating the transmission parameter, whichrealize to support the MIMO multi-user transmission based on thedemodulation reference signal, by adding a new indication signaling,which is used to indicate different joint encoded parameters when thenumber of the enabled transport blocks is different, in the downlinkcontrol information format, thereby.

The system for indicating a transmission parameter in the presentinvention comprises an evolved node B, wherein, the evolved node Bcomprises a multi-user multi-input multi-output (MIMO) data downlinktransmission module, which is configured to: when the MIMO downlink dataare transmitted, use a newly-added indication signaling in a downlinkcontrol information format to indicate different joint encodedparameters when the number of enabled transport blocks is different.

The MIMO data downlink transmission module is further configured to:when a single transport block is enabled, indicating to perform jointencoding on one or more information in the following information:whether diversity is transmitted, a number of transmitted layers,scrambling identity, antenna port, spreading code information, and pilotfrequently information; when two transport blocks are enabled,indicating to perform the joint encoding on one or more information inthe following information: a number of transmitted layers, scramblingidentity, antenna port, spreading code information, and pilot frequentlyinformation; and further configured to use the indication signaling toindicate that information used for performing the joint encoding isdifferent when the total number of the antenna ports is different orreceiver capability of user equipment is different; further configuredto, when the single transport block is enabled, make the antenna portfor single layer transmission indicated by an indication bit of new datacorresponding to disabled transport block be different through differentvalues of the indication signaling; further configured to, when thesingle transport block is enabled, use the indication bit of the newdata corresponding to the disabled transport block to indicate theantenna port for the single layer transmission to be the antenna portsof which all serial numbers are even or the antenna ports of which allserial numbers are odd; and further configured to, when the singletransport block is enabled, use the indication bit of the new datacorresponding to the disabled transport block to indicate the scramblingidentity.

As shown in FIG. 1, the method for indicating a transmission parametercomprises: when data are transmitted under multiple user multi-inputmulti-output (MIMO), using a newly-added indication signaling in adownlink control information format to indicate different joint encodedparameters when numbers of enabled transport blocks are different. Whena single transport block is enabled, it is indicated to perform jointencoding on one or more information in the following information:whether diversity is transmitted, a number of transmitted layers,scrambling identity, antenna port, spreading code information, and pilotfrequently information. When two transport blocks are enabled, it isindicated to perform the joint encoding on one or more information inthe following information: a number of transmitted layers, scramblingidentity, antenna port, spreading code information, and pilot frequentlyinformation. When the total number of the antenna ports is different,the information used when performing the joint encoding is different.For example, the parameter used when the joint encoding design isperformed in the case of four antenna ports is different with theparameter used when the joint encoding design is performed in the caseof eight antenna ports. When the receiver capability of user equipmentis different, the parameter used when performing the joint encoding alsocan be different, for example, the parameter used when the jointencoding design is performed in the case that the receiver capability ofthe UE is four layers is different with the parameter used when thejoint encoding design is performed in the case that the receivercapability of the UE is eight layers.

When the single transport block is enabled, the antenna port for thesingle layer transmission indicated by an indication bit of the new datacorresponding to disabled transport block is different; or the antennaport for the single layer transmission indicated by using the indicationbit of the new data corresponding to the disabled transport block is theantenna port with even index or the antenna port with odd index; or whenthe single transport block is enabled, the indication bit of the newdata corresponding to the disabled transport block is used to indicatethe scrambling identity.

In the above-mentioned method and system of the present invention, thereference signal information can include the reference signal patternand/or the reference signal mode. The reference signal pattern and thereference signal mode are equivalent, and the reference signal patternis corresponding to the unique reference signal mode, while thereference signal pattern can be confirmed through the correspondingreference signal mode. When the joint encoded parameter is indicated,the reference signal pattern or the reference signal mode or thereference signal information can be indicated directly. The number ofthe transmitted layers and the transmitted rank value are equivalent,and the rank values during the multi-user and the single usertransmission represent the number of the layers performing thetransmission to the UE; the antenna port and the index of the layer canbe one-to-one correspondence through the mapping way, and the index ofthe layer can be known through the antenna port used during themulti-user and the single user transmission; the above-mentionedequivalent information also can be obtained through the signaling by theembodiment of the present invention.

In the above-mentioned method and system of the present invention, theinformation of the spreading code includes the length of the spreadingcode and the specific spreading code. In the present embodiment, whenthe joint encoded parameter is indicated, the length of the spreadingcode can be indicated directly, and also the spreading code can beindicated directly, and also the label of the spreading code informationcan be indicated so that the length of the spreading code included inthe spreading code information and the specific spreading codeinformation can be indicated.
